As long as the cat back is after the secondary cat (factory midepipe) this header seteup will bolt on to any of those catback exhaust. I'm bolted up to my factory catback right now. But yes this will not bolt-up to any header back exhaust.

Yea, I have a headerback SRT. I love the sound on it. I think the only way i'm going to be able to get UEL is with AVO's turbo kit.

Please don't take this the wrong way, but could the 6whp gain be from just removing the cat in the front pipe? I know most catless front pipes have dynoed around a 6/7whp gain with stock header. Otherwise the header itself looks great.

That could be it. But how does their power band look? That was 6 peak hp. I gained 10 at the bottem end. And gained all throught the power band. That's where I am most happy.

GRM did a comparo on what removing cats does...essentially no gain. 1-2rWHP from removing as compared to a high flow cats. The gains are probably from the manifold.

Also like I said. I forgot to plug in the 02. It's going back on the dyno later today. So please just wait till that dyno graph goes up.

Well I was able to throw it back on the dyno today. Looks like a gained 1 peak hp. lol The owner thinks the long term fuel trims still needs some time to learn. So he says I can throw it back on at the end of the week. Either way I am very happy. I made 7 peak whp. I gained about 14tq on the low end and 11 hp on the low end. And nothing but gains threw out the whole power band:


Now we took my friend's FR-S (SN:The Slow One)
AFE Takeda Intake
AP Header and Exhaust






Stock tune made 176whp 144wtq:
With Visconti's Stage one tune(tune pre Header and cat back) made 186whp 152wtq


Doesn't look like his header gave him any power at all, ASSUMING his stock base line was like mine. He has no stock dyno runs with the shop we went to. I made 174whp on just an intake and axle back. he has only 2hp over me. That might just be from getting rid of the cats. His tune is what really woke the car up thou.
